Derrick and Kush Chapter 12

Alkali Metals

• very reactive
• can be cut with a knife
• all solid metals
• malleable
• ductile
• react best with halogens(group 17)
• great conductors

Alkali Earth Metals

• can be cut with a knife
• very reactive, but less than alkali metals
• react best with group 16

Transition Metals

• in groups 3-12

Other Metals
Metalloids

• have properties of both metals and non metals. ex: shiny but not a good conductor of electricity

Nonmetals

• dull(not shiny)
• insuators
• less nonmetals than metals on periodisc table

Halogens (nonmetals)

• in group 17
• Very reactive

Noble Gases(nonmetals)

• not very reactive
• all gasses at room temperature
• in group 18

Hydrogen

• simplest element
• element 1

lab notes

• litmus paper turn red when put into acids and blue when put ino a base
• cabbage juice turns liquids red if acid or blue is base. act the same way as litmus paper.
• chemicals used: sodium bicarbonate, white vinegar, amonia, creamer, sodium chloride, and laguna house cabbage juice and water.

is it a base or acid????
sodium bicarbonite=base
amonia=base
white vinegar=acid
creamer=base
sodium chloride=base
